Somehow it doesn't seem fair that you the daughter-in-law have all the responsibility. Whats the matter with the daughter? Are there any other relatives? I took in my sister in 1990 and she lived with me for 5 years until sshe died. She had MS and developed dimentia the last 2 years. It was a nightmare and I like you, sometimes screamed at her and I cry at night to this day about not being nicer and more patient when she would empty her diapers into the drawers, the heating vents etc. It was as if she were gone and this entity took her place. I feel for you and hope you can find some help. I nearly lost my mind. Its so hard to be what you want to be to these people. I will pray for you and hope you find relief soon.
